Digital Sun Sensor

The nanoSSOC-D60 is a AAC SpaceQuest developed two-axis and low-cost sun sensor for high accurate sun-tracking, pointing and attitude determination. With minimum size, weight and power consumption it is the perfect ADCS solution for your nanosatellite

The Sun Sensor on a Chip (SSOC) architecture, achieved through a MEMS fabrication process, results in a highly integrated sensing structure providing accurate and reliable sun-tracking, pointing and attitude determination. The SSOC device measures the incident angle of the sun’s rays in two orthogonal axes, alongside other information useful for attitude determination, via client optional UART, I2C or SPI communication protocol, leveraging the geometrical dimensions of the design to provide high sensitivity in a form factor perfect for small satellites.

SSOC technology has been qualified on different tests, including radiation (absorbed dose and proton beam), random vibration, shock response, outgassing, thermal and EMC.

Every sensor is calibrated, characterized, and provided with a look-up table. The use of a metal shield and cover glass over the optical eye minimizes ageing in higher radiation environments.

With over 630 units delivered, and flight heritage on-orbit accumulating since 2009, the nanoSSOC-D60 is the perfect ADCS solution for your nanosatellite.
